Digital Design Design for a digital system Digital Design Software design Hardware design Digital Design Integrated Circuit (IC) 1960 1966 1971 Digital Design Integrated Circuit (IC) Moore’s Law: doubled in 18 months Digital Design Integrated Circuit (IC) SOC: System on chip SIP: System in package SOPC: System on programmable chip Digital Design ASIC: Application Specific Integrated Circuit Function , cost , speed , efficient Digital Design How to design a digital system How to optimize your design How to make your design more efficient The arrangement of the text Teach in 32 times: Basic design Char.1,3,4 5 Combinational design Char.2,4,6,9 15 Sequential design Char.7,8 12 Exercise and Exams : 100 Design practice: 30 Middle exam: 30 Final exam: 40 Chapter 1: Digital design with standard form Digital system and its truth table Digital signal How are you! 1001000 1101111 1110111 0100000 1100001 1110010 1100101 0100000 1111001 1101111 1110101 0100001 Any digital signal is with limited states, all the states can be listed in a table. The property of digital signal For each input state, an output state can be set; System can be listed in a table: Truth table. Combinational system Digital design: Truth table A device with majority judge function  output the majority input state . 4-bits prime-number detector when input is (2,3,5,7,11,13), the output is 1, otherwise the output is 0 . Digital design: Truth table 4-bits LSB+1 adder Digital design: Truth table
